We empirically evaluate lightweight moment estimators for the single-pass quantile approximation problem, including maximum entropy methods and orthog...
We consider the information extraction framework known as document spanners and study the problem of efficiently computing the results of the extracti...
Window aggregation is a core operation in data stream processing. Existing aggregation techniques focus on reducing latency, eliminating redundant com...
